Title: Resin-fibre sheets nitro-imidazole derivatives
IPC: D04H13/00
Filed: 1972-02-11
Abstract: 1437081 Laminates comprising bonded fibrous material K KICHLU 11 May 1973 [11 Feb 1972] 6545/72 Heading B5N [Also in Division D1] A laminate comprises a backing layer and a layer of natural animal or vegetable fibres having an average length of at least 3 inches adhered to the backing, the fibres having been pressed into sheet form and being held together by 3 to 20% by weight of the fibres of a cured resin in the fibrous layer, which resin may also impregnate the backing. The backing may be paper, cardboard, cloth, hardboard or chipboard or a batt of natural fibres. The fibres may be "hard" fibres, i.e. leaf fibres such as sisal, manilla hemp and copra. Alternatively ramie or jute fibres may be used. The majority of the fibres may be 8 to 12 feet long. A layer of the fibres can be formed by embedding a sliver or tow of the fibres in beeswax, allowing the wax to set and cutting a "slice". Alternatively a mass of the fibres, optionally mixed with 1 cm. long crimped polyester fibres is needled or bonded together. The fibres may be woven into a fabric. The fibrous layer may be formed on the backing or on a release paper. Thus a 1 fibre thick layer of parallel adjacent fibres may be laid on the backing by hand or in a continuous process in which a chipboard backing is moved along a production line and fibres are laid and the fibres and board sprayed with resin. The backing can be sprayed with resin before the fibres are deposited. The fibrous layer is laminated to the backing by hot pressing, e.g. 250 to 230 lbs./in.<SP>2</SP> at 150 C. for 8-10 minutes. In one embodiment a backing layer is sandwiched between 2 fibrous layers containing resin a smooth plate placed below one layer and brown paper or corrugated cardboard placed above the other layer and the layers hot pressed to give a laminate with one smooth and one uneven surface. Alternatively suitably surfaced rollers may be used to laminate. The resin may be a urea, melamine or phenol formaldehyde resin or a polyester resin. Ammonium chloride may be used as curing catalyst. Sufficient resin may be used to completely embed the fibrous layer. A lacquer of polyurethane, nitrocellulose or melamine may be applied to seal part or all of the fibrous surface. The laminates are used as wallpaper, floor coverings and simulated wood products. The backing may have a pressure sensitive or heat or water activatable adhesive on its rear surface.

Title: Improvements in or relating to oxide cathodes
IPC: H01J9/04
Filed: 1960-03-03
Abstract: 947,999. Cathode materials and processing. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 3, 1960 [March 6, 1959], No. 7567/60. Heading H1D. In a method of manufacturing a nickel support for the electron-emissive layer of an oxide cathode, which support contains inter alia magnesium as impurity, oxygen is caused to diffuse into the nickel from the non-emissive surface portions, during heating at 1000 to 1200 C., until the magnesium present in the nickel has been bound by oxygen throughout the greater part, but not the whole of the thickness of the support. The nickel support may contain 0.05 to 0.06% by weight of Mg, 0.0101/0 Si, 0.02% Fe and 0.01% Mg, the emissive layer comprising equal parts of barium and strontium oxides. If the support is tubular, having a wall thickness of 0.1 mm., oxygen may be caused to diffuse into it by passing air therethrough and heating at 1100 C. for 20 mins., the outer surface of the tube, which is later coated with emissive material, being kept in an inert atmosphere of nitrogen, or in a reducing atmosphere. Alternatively, the non-emissive surface portions may be provided with a 0.1 mm. layer of nickel oxide, from which, during heating at 1100 C. for 10 mins, in an inert atmosphere or in vacuo, oxygen is liberated and diffuses into the nickel. The nickel oxide layer also insulates the cathode from its associated heater and the heating process can coincide with the activation of the emissive layer after mounting the cathode in a discharge tube.

Filed: 1936-03-13
Abstract: 475,409. Brick &c. kilns. GEYER, A. March 13, 1936, No. 7672. [Class 51 (ii)] In a continuous multichamber kiln for burning bricks &c. of the kind in which each chamber 1 is fitted with rail tracks 3 permitting the introduction and withdrawal of trollies 4 carrying floor sections 5 on which the goods 6 are loaded, alternate chambers are connected by fire-connection flues to provide a double fire circuit. The layout shown in Fig. 1, comprises two banks of chambers 1 provided with rail tracks 3 with which are associated transfer tracks 8 serving for the passage of the trollies 4 from the machine house 9 to the kiln chambers and from the latter to a storageground 10 or loading-place 11. In the double-bank kiln shown in Figs. 1, 15 the goods are introduced into the chambers through the adjacent ends 44 and withdrawn through the opposite ends 45. Each chamber 1 has supports 7 on to which the floor sections 5 can be lowered to permit the trollies to be withdrawn during the drying and burning. When the raw goods possess sufficient rigidity, they are stacked directly on one another, as shown in Fig. 7, but in the case of, for example, wire cut bricks, pallets 16, Fig. 9, each carrying four layers of bricks, are employed, the chamber walls being formed with abutments 15 to support the ends of the pallets when the floor sections 5 are lowered. The pallets are carried by members 17, Fig. 11, mounted on standards 18, the raising and lowering of the sections 4 being effected by two jacks 25 operated simultaneously by a hand-lever 26. To enable the pallets 16 to be readily removed after the drying operation has been completed, the floor sections 5 are provided with elevated portions 28 extending upwardly between the pallets, or alternatively, the lower layer of bricks may be stacked in the manner shown in Fig. 11, in connection with the next higher row of pallets 16. The fire flues connecting alternate chambers 1, 2, 3 .... 16 and 1a, 2a, 3a .... 16a of the kiln are shown at 46, Fig. 15, while, in the roof of each chamber there is provided a hot-air flue 49, Fig. 2, these flues communicating with main hot-air flues 50 running parallel with the outer sides of each bank of chambers. Movable pipes 51 serve, when in the position shown in Fig. 2, for the supply of fuel, and when raised permit communication between a chamber and its hot-air flue 49. Smoke or damp-air flues 48, Fig. 2, open into the end portions 47 of the chambers in which a wicket is built up to prevent, when a chamber is in fire, the passage of fire into the flues 48. Modifications are described in which the invention is applied to kilns consisting of a single bank of chambers only. Specifications 446,936 and 476,928 are referred to.
